1 .6 CONSTRUCTION NEAR UTILITY SYSTEMS

All contractors shall be responsible for processing their own Work Clearance Request (AF Form I 03), commonly known as a "Digging Permit," and coordinating with Government inspectors as required. It is also the sole responsibility of the Contractor to make all requests for locates and marking by the private sector. Note that private companies supply numerous utilities and services on Malmstrom Air Force Base. AF Form 103 does not address coordination with private companies. Requests for locates by private firms shall be performed by the contractor in accordance with State of Montana and Federal regulations. The Contractor is responsible for obtaining all coordination signatures for the permit. The approved permit shall be valid for a period not to exceed 90 calendar days. TO THE MAXIMUM EXTENT POSSIBLE, ELIM INATE PERMANENT MARKINGS ON PAVEMENT AND CURBS. The contractor shall be responsible for maintaining all utility markings. Location marks shall be removed after 14 calendar days if not used. All markings shall be accomplished with water-based chalk (Aervoe Pacific Inc. 1-800-227-0196 or equal). No paints will be used. Detailed permit procedures and guidelines shall be provided to the contractor during the Pre-performance Conference. Digging within three feet of buried communications cables, environmental monitoring wells, electrical cables, irrigation systems, and gas lines shall be performed by hand digging until the utility is exposed. The Project Inspector shall be notified three days prior to digging within a three-foot area near this utility. A representative from communications (Telco) must be present during excavation of Communications Cables. The cable piping routes must be marked prior to excavation in the area. The Contractor shall be held responsible for any damage to a marked or identified utility by excavation procedures. Once the utility is exposed, mechanical excavation may be used if there is no chance of damage occurring to the cable or piping system. The contractor is responsible for marking all excavations he will do, three (3) work days prior to needing existing utilities marked by the government.

1 .7 WORK SCHEDULE

Working hours for the Contractor will normally be between the hours of 7:45 a.m. and 4:15 p.m.

excluding Saturdays, Sundays, and Federal Holidays. If the Contractor desires to work during periods other than above, additional government inspection forces may be required. The Contractor must notify the Contracting Officer three days in advance of his/her intention to work during other periods to allow assignment of additional inspection forces when the Contracting

Officer determines that they are reasonably available. If such force is reasonably available, the Contracting Officer may authorize the Contractor to perform work during periods other than normal duty hours/days. However, if inspectors are required to perform in excess of their normal duty hours/days solely for the benefit of the Contractor, the adjustments to the contract price may be made periodically as directed by the Contracting Officer.

1.8 ANTI-TERRORISM (AT) AWARENESS TRAINING.

In accordance with AFI 10-245, Antiterrorism (AT), the Government will ensure that AT level-1 awareness training is offered to all contractors. The objective of the training is to provide personnel with requisite knowledge necessary to remain vigilant enable employment of AT tactics, techniques, and procedures.
